title: Luminescent amphiphilic 2,6-bis(1,2,3-triazol-4-yl)pyridine-platinum(II) complexes: synthesis, characterization, electrochemical, photophysical, and Langmuir-Blodgett film-formation studies.
abstract: A new series of platinum(II) complexes with tridentate ligands 2,6-bis(1-alkyl-1,2,3-triazol-4-yl)pyridine and 2,6-bis(1-aryl-1,2,3-triazol-4-yl)pyridine (N7R), [Pt(N7R)Cl]X (1-7) and [Pt(N7R)(CCR')]X (8-17; R=n-C4 H9 , n-C8 H17 , n-C12 H25 , n-C14 H29 , n-C18 H37 , C6 H5 , and CH2 -C6 H5 ; R'=C6 H5 , C6 H4 -CH3 -p, C6 H4 -CF3 -p, C6 H4 -N(CH3 )2 -p, and cholesteryl 2-propyn-1-yl carbonate; X=OTf(-) , PF6 (-) , and Cl(-) ), has been synthesized and characterized. Their electrochemical and photophysical properties have also been studied. Two amphiphilic platinum(II)2,6-bis(1-dodecyl-1,2,3-triazol-4-yl)pyridine complexes (3-Cl and 8) were found to form stable and reproducible Langmuir-Blodgett (LB) films at the air/water interface. These LB films were characterized by the study of their surface-pressure-molecular-area (π-A) isotherms, XRD, and IR and polarized-IR spectroscopy.
